i have a dataframe, which i want to show by tabulate:
| f_45 | 1.6 | 1.6 | 1.6 |
| f_46 | -3.0 | 3.0 | 3.0 |
| f_47 | 2.8 | 2.8 | 2.8 |
| f_48 | 2.5 | 2.5 | 2.5 |
| f_49 | -3.0 | 3.0 | 3.0 |
| f_50 | 1.5 | 1.5 | 1.5 |
| f_51 | -0.5 | 0.5 | 0.5 |
| f_52 | -0.1 | 0.1 | 0.1 |
| f_53 | -1.1 | 1.1 | 1.1 |
| f_54 | -2.2 | 2.2 | 2.2 |
| f_55 | -8.6 | 8.6 | 8.6 |
| f_56 | 8.1 | 8.1 | 8.1 |
| f_57 | 6.5 | 6.5 | 6.5 |
| f_58 | 6.3 | 6.3 | 6.3 |
| f_59 | 5.5 | 5.5 | 5.5 |
| f_60 | 5.5 | 5.5 | 5.5 |
| f_61 | 2.5 | 2.5 | 2.5 |
| f_62 | -3.1 | 3.1 | 3.1 |
| f_63 | -1.3 | 1.3 | 1.3 |
| FillNa(DecayLinear(XH::voi_ratio,10)) | 7.8 | 7.8 | 7.8 |
| FillNa(Diff(SmartPrice,2)) | 7.7 | 7.7 | 7.7 |
| FillNa(Div(SignedSqrt(Ewma(XH::voi,0.8)),WSpread)) | 3.8 | 3.8 | 3.8 |
| FillNa(Div(SignedSqrt(Ewma(XH::voi_ratio,0.8)),WSpread)) | -3.3 | 3.3 | 3.3 |
| FillNa(Sub(XH::shadow_mid(10),AvgPrice)) | -6.7 | 6.7 | 6.7 |
| FillNa(Sub(XH::shadow_mid(10),Wmid(0))) | -0.4 | 0.4 | 0.4 |
| XH::high_low_dist(10) | 2.0 | 2.0 | 2.0 |
| XH::high_low_dist(30) | 2.1 | 2.1 | 2.1 |

| R2 | 202.6 | 202.6 | 202.6 |

please see the index column.
there are several columns whose length is large, can i set something to limit the width?

Yes, you can set the width of rows and columns:
#include "tabulate.hpp"
using namespace tabulate;
int main() {
Table table;
table.add_row({"Quantity", "Value"});
table.add_row({"FillNa(Div(SignedSqrt(Ewma(XH::voi_ratio,0.8)),WSpread))", "-3.3"});
// set the width of the first column
table.column(0).format().width(40);
std::cout << table << std::endl;
}
+----------------------------------------+-------+
| Quantity | Value |
+----------------------------------------+-------+
| FillNa(Div(SignedSqrt(Ewma(XH::voi_ra- | -3.3 |
| tio,0.8)),WSpread)) | |
+----------------------------------------+-------+
